Antibiosis
Antibiosis (pronunciation: an·ti·bi·o·sis, /ˌæntɪbaɪˈəʊsɪs/) is a biological interaction between two or more organisms that is detrimental to at least one of them. The term is often used in the context of the relationship between a host organism and a pathogen.
Etymology
The term "antibiosis" was first coined in the early 20th century. It is derived from the Greek words "anti", meaning "against", and "biosis", meaning "life".
Definition
In microbiology, antibiosis refers to the antagonistic association between two organisms in which one is adversely affected. This is often due to the production of a chemical substance by one organism that is harmful to the other. A common example of this is the production of antibiotics by certain bacteria, which can inhibit the growth of other bacteria.
